I opened command prompt admin and it says "system32". i didn't think to check if this S3 from 2015, after the SP4 came out, I think, is 64bit architecture. some people can astound by the ridiculous things they do. i assume Microsoft launched this 32bit then, but as i recall the transition to 64bit happened years earlier, except for S3, again, i assume. so i may have to sell it if i can't get the latest Linux kernel and firewall features. but so far, it works very well and the micro USB charger system and battery life are amazing. I am not having any issues with it accept learning to navigate things like screen shot and left click is clicking on the center of the left side of the mouse pad.
I am going to see if I can get some modern software to work on it.
